Group signatures in practice
10 páginas, 2 figuras, 1 tabla. International Joint Conference. CISIS’15 and ICEUTE’15Group signature schemes allow a user to sign a message in
an anonymous way on behalf of a group. In general, these schemes need
the collaboration of a Key Generation Center or a Trusted Third Party,
which can disclose the identity of the actual signer if necessary (for exam-
ple, in order to settle a dispute). This paper presents the results obtained
after implementing a group signature scheme using the Integer Factoriza-
tion Problem and the Subgroup Discrete Logarithm Problem, which has
allowed us to check the feasibility of the scheme when using big numbers.This work has been partially supported under the framework of the international
